Title: Sensor for detecting local magnetic fields
Inventor: LOREIT UWE
IPC: G01R15/20
Filed: 1985-03-05
Abstract: The arrangement according to the invention is used for detecting local magnetic fields by using a magnetic field sensor. It can be used as probe with a high spatial resolution, for example for measuring the current flow in conductor tracks on printed circuits. It was the aim of the invention to create a handy, highly sensitive point probe. The object of the invention, to create an arrangement which can be used as measurement transducer for magnetic fields of conductor surfaces, which is not influenced by external magnetic interference fields and temperature fluctuations, is achieved by the fact that, for the purpose of decoupling a measurement signal from the influence of extended fields, the arrangement has a magnetic field sensor in the form of a thin strip-shaped magneto-resistive element, means for linearising the magneto-resistive effect and for reducing the temperature sensitivity and a plate-shaped body of high magnetic conductivity, which has an area dimension which corresponds to a multiple of the magneto-resistive element and is located at a distance of at least the strip width of the latter away from the latter. The magneto-resistive element is advantageously constructed as bridge circuit of four magneto-resistive microstrip lines.

Title: Programming stencil with marking notches
Inventor: STUEBEN PAUL
IPC: B43L7/08
Filed: 1985-05-20
Abstract: The invention relates to a programming stencil for laying out endless forms, especially for computer output printed lines and data acquisition lines with division for one or more characters. It is known for programming rulers to be used, having scales with the required gradations printed on the edges, to satisfy the requirements regarding printing accuracy in the laying out of endless forms which are written on by computer printers. If the gradations are to be transferred to the paper to be laid out, a line is to be drawn on the said paper at the level of a measuring line. In this process, inaccuracies occur during transfer and, furthermore, this process is time-consuming when long printed lines are marked. The object of the invention is to transfer the markings to the paper to be laid out more accurately and more rapidly. This object is achieved according to the invention by cutting small tooth-like marking notches into the edges of the stencil. If the user marks the edge of the stencil with a pencil, the line generated at the point of a marking notch is marked by a small bulge.

Title: Two-stroke internal combustion engine controlled by rotary slide valve
Inventor: BAUMEISTER WILHELM
IPC: F01L7/12
Filed: 1985-09-02
Abstract: The subject of the application is a two-stroke internal combustion engine controlled by rotary slide valve, with rotary slide valve housing attached to a wall of the crankcase. A circular segmental rotary slide with a closing edge leading in the direction of rotation and an opening edge trailing in the direction of rotation and rotationally fixed to the crankshaft is arranged in this housing. An inlet opening with control edges on both sides in the direction of rotation of the rotary slide valve is arranged in the wall of the crankcase, and in the opposite wall of the rotary slide valve housing an intake opening with control edges lying opposite the inlet opening. Such an engine is to be improved in that the inlet path in the area of the rotary slide valve is controlled as a function of the speed by adjustment of those parts which do not rotate with the rotary slide valve and consequently can still be controlled even at high speeds. To this purpose at least one of the control edges in the wall of the rotary slide valve housing is displaceable relative to the corresponding control edge of the inlet opening of the crankcase as a function of the speed of the crankshaft.

Title: Flowmeter
Inventor: ROTH HANS-WERNER DR ING
IPC: G01F1/40
Filed: 1986-10-11
Abstract: The flowmeter serves for a volumetric measurement of an air flow. It is formed by a probe (1) which extends linearly over a certain longitudinal section transversely to the flow direction (2) and has an orifice (100) arranged transversely to the flow direction and having a rectangular flow cross-section. The side walls (3, 4), extending in the flow direction (2), of the orifice initially give a narrowing (5; 21, 22) of the cross-section and then a widening (6; 21', 22') of the cross-section. In the vicinity of the narrowest flow cross-section (14), chambers (7, 8) are located on the side walls. One chamber (7) has, on its end face (9) pointing against the flow direction (2), orifices (10) for picking up the total pressure (pt), and the other chamber (8) has, in the vicinity of the narrowest flow cross-section, orifices (13) arranged perpendicularly to the flow direction (2) for picking up the static pressure (pst). These pressures are fed to a measuring or control instrument (20) for deriving a signal which indicates the volumetric flow. <IMAGE>

During removal, the disc (12) is rotated back into its original position again by means of a prestressed spiral spring. <IMAGE>
Patent DE-3702451-A1 (DE)
Inventor: BEYER ECKHARD DR ING
IPC: B23K35/38
Filed: 1987-01-28
Abstract: When materials are worked with a laser beam (11, 12), a plasma (14) is formed at high beam output. On account of its absorption of the laser light, this plasma (14) hinders the transfer of energy to the work piece (10). In order to render harmless the electrons mainly responsible for the absorption, helium, which promotes the recombination of electrons and ions, is blown onto the working point (13). Instead of the expensive helium, this invention uses the readily available gases CF4 and/or SF6. Together with a filling gas/inert gas to which they are admixed at less than 25%, they are blown (16) via a nozzle (15) onto the working point (13), where, under the effect of the high temperature, they form highly electronegative fluoro-radicals which remove electrons from the plasma (14). This process can be controlled via the mixture composition. The method described is especially suitable for working metals, in particular aluminium alloys. <IMAGE>
